What would you improve?

This is very, very awesome.... Well done! Not many can do Hi Key Photography well ("me" included in that many!) but this image delivers.. One slight suggestion? The very large highlight on the knife blade throws it out of balance by a tad - so, if you reduced the highlight to mimic more of what we see on the fork (bringing it down to more of a wider line), maybe it will work better?

Also - just a nit. Watch for CA in Post processing in the shadows as they transition to white. You can fix that in LR - or, just select those areas and desaturate the color - either technique will have the same effect... Anyway -

Good for you for trying this. Great technique and superb results. Congrats!
